Hello,
I am using ScaLapapck from MKL.
Is there a PZLAHRQ routine in MLK?
The reference manual says it has only a real version https://software.intel.com/en-us/node/521530
If no, then how can I do a Schur decomposition of a complex, non-hermitian matrix in Hessenberg form?
Thanks,
Alex

Alex,
it seem we missed to declare this API into doc ans header files. see the nm log parsing:
# nm libmkl_scalapack_lp64.so | grep pzlahqr
00000000002b5440 T pzlahqr_
00000000008c13c0 b pzlahqr_$ICURCOL.0.1
00000000008c1340 b pzlahqr_$ICURROW.0.1
00000000008c14c0 b pzlahqr_$K1.0.1
00000000008c15c0 b pzlahqr_$K2.0.1
00000000008c1540 b pzlahqr_$KCOL.0.1
00000000008b10c0 b pzlahqr_$KP2COL.0.1
00000000008b1040 b pzlahqr_$KP2ROW.0.1
00000000008c1440 b pzlahqr_$KROW.0.1
00000000008b1140 b pzlahqr_$S1.0.1
00000000008c1640 b pzlahqr_$SMALLA.0.1
00000000008c5e40 b pzlahqr_$VCOPY.0.1
You may try to add this API to the header files by himself. hope that helps.
